If you a have a DVM it would be worth looking at each battery and see if they track or one has a shorted cell that might cause it to charge harder than necessary. Mine was completely replaced about a year ago after I was seeing excessive temps on all devices including the transformer (and you could smell the varnish burning) they swapped it. Bad xformer.
Either way, I see higher FET temps than that on a normal hard charge, as in C/10 on a 60% discharge. But it doesn't go into fail safe
I do have DVM and will isolate the two batteries and check them. The little charger has gone into 'maintenance' mode from 'charge' mode but I measure 12.2 V at the batteries. I will check voltage on each one.
I am curious though....even though I have the charging feature of the inverter turned off, the inverter is passing voltage (via its internal transfer switch)thru to the 110VAC devices in the coach on the inverter circuits. Doesn't the inverter also serve to 'convert' incoming AC to 12 V DC for the lighting, etc? If so, even with dead house batteries, as long as I have shore power, would I not have 12V DC for the coach??
